data.dta contains the water consumption data and survey data used in the estimations.
Run Estimations_r to create data_wide.dta and data_long.dta. 
Then run predictedm3_r with data_long.dta to create predictedm3.dta.
predictedm3.dta is used in welfare do-files.
Engineering estimate is calculated in Excel. Disadoption calculations are done in Excel.
